KamitKami is a python script which takes as input 2 files of foo.css and bar.html and outputs 
a smaller bar_foo.css file to be included in bar.html . bar_foo.css has only the elements used in bar.html
and no more. This helps the site to load faster.

python kamitkami.py foo bar

YET TO DO
1. Find list of css format to be kept according to https://www.w3schools.com/cssref/css_selectors.asp from the html included tags, classes and keep only those.
2. Create loop over folder for multiple css file generation.
3. Minify generated css optionally by keeping a keyword.
4. Remove dependency of bs4 and use html.parser already in python.

Defer
Find id tags which exist in html
